My YouTube video review of the Intelligent DJI TELLO Battery Charger
Quick review for a cheap smart Tello battery charger, for the DJI Ryze Tello Mini Quadcopter.
I've owned this intelligent battery charger for over 6 months, and its worked perfectly for that amount of time. It charges up to 3 batteries for the DJI Ryze Tello at the same time, and saves you quite a bit of time in doing so. You can see each battery slot independently so you know there working correctly. If your into flying your quadcopter a lot, its best to have a few batteries fully charged on hand, so you get to enjoy your quad a bit more.
